⚠️ Common Signs of Failure

• Coolant or oil weeping from a crack in the casting
• Persistent low oil pressure traced to worn or damaged main bearing bores
• Coolant in the oil, or oil in the coolant, with the head and gasket proved sound
• Damage after a thrown connecting rod, a seizure or a dropped valve
• On strip-down, cracks, corroded core plug bores, stripped fixing threads, or bores machined beyond limits

🛠️ Service Notes

• Listed as the Stage 2 and Tier 2 standard version for engines from serial number 5301077757 onwards - emissions stage and serial number must both match
• Building up a crankcase is a full engine rebuild, so plan for bearings, seals, gaskets and a machine-shop check of the bores
• At 229.5 kg this needs lifting equipment and freight handling rather than a parcel carrier
